Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00044 | $0.00509 |
| Opus 5 | $0.00022 | $0.00254 |
| Sonnet 5 | $0.00009 | $0.00102 |
| Haiku 4.5 | $0.00004 | $0.00051 |
Grade A, and why
security-review scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Security Review
Invoke the security-reviewer agent to assess security-sensitive changes.
When to trigger
- Child process spawning or lifecycle changes (
src/lsp-client.ts) - File system read/write operations (
src/file-editor.ts,src/file-scanner.ts) - Configuration file loading or parsing (
cclsp.json,CCLSP_CONFIG_PATH) - Environment variable handling
- New or modified LSP server adapter (
src/lsp/adapters/) - Setup wizard input handling (
src/setup.ts)
Review checklist
- Command injection: Are user-supplied values (config file paths, server
commands) sanitized before being passed to
child_processspawn? - Path traversal: Can file paths from LSP responses escape the project
root? Are
file://URIs validated before resolving? - Resource exhaustion: Are there timeouts on LSP server responses? Can a malicious LSP server cause unbounded memory growth?
- Config trust boundary: Is
cclsp.jsontreated as trusted input? What happens if it contains unexpected fields or types? - Process cleanup: Are child processes reliably terminated on shutdown? Can orphaned processes persist?
- Symlink attacks: Does file resolution follow symlinks outside the project directory?
How to invoke
Use the everything-claude-code:security-reviewer agent via the Task tool:
Task(
subagent_type: "everything-claude-code:security-reviewer",
prompt: "Review the following changes for security concerns: <describe changes>"
)
Output expectations
The security reviewer should produce:
- CRITICAL: Must fix before merge (injection, traversal, credential leak)
- HIGH: Should fix before merge (missing timeouts, incomplete cleanup)
- MEDIUM: Fix when possible (defensive checks, hardening opportunities)
- LOW: Informational (best practice suggestions)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

security-review is a skill published in the GitHub repository ktnyt/cclsp (673 stars, last pushed 6mo ago), licensed MIT. It adds 44 tokens to every session and 509 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
